This is not big snake, little more than 1 m. Where your snake came from - this is very complicated question, this species have tremendous areal and the same patterns and color diversity, therefore, if you dont know exact locality of your snake, you must see fotos of this species (there is several site in internet - Wim, my and Sacha Korrell).
